Entrained gases of any kind in liquid processing systems can cause system problems such as pressure surges, overworked pumps, water hammer, deadhead, siphoning and pump failure. According, processor vent gases are vented from liquid processing systems through degassing valves which are disposed in fluid lines. When the liquids or gases being processed or produced are corrosive, such as for example, sodium hyperchlorate, hydrochloric acid or ozone, degassing valves are subject to more repaid degredation and failure which can lead to the aforementioned system problems. Moreover, it is desirable to have degassing valves which are readily repairable on site or are readily replaceable in order to avoid costly processing delays.
While the aforementioned problems occur primarily in system lines, tanks enclosing corrosive liquids are faced with similar problems and is desirable to provide degassings for enclosures, which vents resist corrosion are easy to repair.
Current degassing valves provided for these purposes do not adequately address the problems of corrosion and reparability. Consequently, there is a need for such degassing valves.
